Pew Survey: Most 'Millenials' Lean Left

Fifty percent of Americans 18 to 33 years old said they are political independents and more are Democratic leaning.

Thirty-four percent said they lean Republican.

"It's not that they don't have strong political opinions, they do," Pew Executive Vice President Paul Taylor said. "It's simply that they choose not to identify themselves with either political party."

"They believe in a big activist government on some of the social issues of the day - gay marriage, marijuana legalization, immigration. Their views are much more aligned with the Democratic Party," he said.

They are also less attached to organized religion. Sixty-four percent don't consider themselves "religious" - the highest for any age group ever measured.

Also, only 1 in 4 is married. The numbers differ drastically from baby boomer, of which almost half were married at that age.
